Functionality in Women with Breast Cancer: The Use of International Classification of Functioning, Disability and Health (ICF) in Clinical Practice

[Purpose] The aim of this study was to evaluate the functionality of women diagnosed with breast cancer according to the International Classification of Functioning, Disability and Health (ICF). [Subjects and Methods] This was a cross-sectional study. We applied instruments consistent with the summary of ICF codes for breast cancer: quality of life questionnaire (WHOQOL), upper limb symptoms and function (DASH), social support, physical examination and functional medical record data. [Results] The study included 105 women who were 55 years old and subjected to surgical treatment within an average of 1.63 year previously. The 'function' component considered in the WHOQOL, the DASH and physical examination. There were high prevalences of positive responses for most codes, and only b130, d430, d445, d640, d650, d920 and codes of environmental factors considered by the Social Support Questionnaire showed high prevalences of negative responses (47.6%, 61%, 43.8%, 63.8%, 56.2%, 52.4%, and 35.2%, respectively). [Conclusion] There was a lower prevalence of disability, with the exception of issues related to strenuous activity and load. Some findings showed conflicting results between different instruments that measure the same code, and studies that propose more accurate tools and are able to consider the ICF codes specific to this pathology are necessary.
